Mechanism for the adjustment of the direction and of the amplitude of the movement of the transporting claw for material to be sewn on a sewing machine |
摘要 |
A mechanism for a sewing machine for enabling the manual or automatic control of the direction and of the amplitude of movement of a transporting claw guide for material to be sewn. The mechanism is driven from the main driving shaft of the sewing machine via a cam and a series of intermediate lever members connected to a rotatable shaft connected to the transporting claw guide. The control is automatically accomplished by means of a cam driven from the main driving shaft of the machine via the arrangement of levers to obtain back-and-forth movement of the claw guide or, when a cam follower is disengaged from the cam, the control can be accomplished manually without the automatic back-and-forth movement.
